I have since left selling BMWs. I really miss my job. And my income was steadily raising as well.

Biggest factor is you will need to find a sales team (Coworkers and Manager) that you vibe with. Mine was always against me and it just made going to work suck. I am pretty sure that when I am older and dont need 100% steady income I will go back to selling cars. But for now, I am going to stick to hourly/salary jobs for me and my family.
